IMPROVEMENT IN FEED-REGULATORS.

Specification forming part of Letters Patent No. 183,684, dated October24, 1876; application filed July 27, 1876.

To all whom it may concern:

Be it known that I, FRIIDERIGH KLINKER- MANN, of Aurora, Dearborncounty, Indiana, have invented a new and useful Feed-Regulator forMillstones, of which the following is a specification The subject ofthis patent is a mechanical device which constitutes a forced orpositive, and at the same time adjustable, feed for grinding-mills.

In the accompanying drawings, Figure 1 is a transverse section of myfeed and regulator in position. Fig. 2 is a longitudinal section of thesame, the regulator being wholly retracted. Fig. 3 is a face view of theslotted plate. Fig. 4 represents my feed and regulator removed fromtheir casting, the regulator being fully retracted.

A and B may represent portions of the bedstone and runner of agrinding-mill. The balance-rynd 0 has a square or other non-circa larsocket, c, for the correspondingly-formed lower extremity dot a rod, D,whose upper extremity is firmly secured, by set screws E or otherfastening, in sleeved extremity F of the shaft G of a bevel-wheel, H,that gears with bevel-wheel I. The shaft J of bevelwheel I has a pinion,K, that gears with a spur-wheel, F, upon horizontal shaft M, which shaftis armed with my feed or wallower N,

consisting of a series of equidistant radial blades, 0, having lips orflanges 0, which point in direction of the rotation of said wallower.Fitting said wallower, and capable of being slid in or out thereupon, soas to contract or to enlarge the effective surfaceof the wallower, is myregulator P. The said regulator is a hollow cylinder, whose inner head Qis perforated, as at q, to snugly fit the hub or shaft M and the radialblades 0 of the wallower. It represents the hopper-spout, whose extendedcheeks S constitute the casing. T represents the lower end of thehopper. The regulator P is drawn out or pushed in by means of a rod, V,which is capable of axial rotation, and, being of elliptical transversesection, can, by a partial rotation right or left, be made capable offree longitudinal movement in the slot 1; of plate V, or can be tight-1y jammed in said slot, and be thus securely retained to its adjustment.

The operation of my device is as follows: The regulator P being set inor out, to correspond with the desired amount of feed, the wallower,rotating as per arrow, forces the feed in definite volume and velocity,at first upward and then outward, through the vent X, whence it dropsinto the eye of the millstone. The shaft Gr, while feathered at 9, so asto compel the rotation of the wheel H, is, at the same time, capable ofsliding freely up or down therein, and consequently the feeder is notdisturbed by any vibrations of the mill. The screws E being temporarilyslackened, the rod D can be elevated or depressed to suit thebalance-rynd, which having been done the tightening of the screws holdsthe rod in place. The rod V is coupled to the regulator through themedium of yoke W, which straddles the grooved portion of shaft M, asshown in Fig. 2. The lips or flanges 0 are useful in giving the blades 0a cupped form, which enables them to lift the grain with greatereffectiveness and regularity.

I do not claim a sliding regulator to millstone-feeds, such regulatorsbeing old; but

I claim as new and of my invention 1. The bladed up-feeding wallower N O0, in combination with the sliding regulator P Q q, substantially as andfor the purpose set forth.

2. In combination with the sliding regulator P Q q, the elliptical rod Vand slotted plate V o.

In testimony of which invention I hereunto set my hand.
